divided 16 into 3 equal parts. i bet you didn't think that was possible i know a physicist that didn't think it was possible. we are rocket scientists. half of you count 16, half do the t high. you can do it. first you try the 16. don't do the t high yet. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16. 1, 2, 3, 4, 5, 6, 7, you keep counting 16. you guys do this. you will start 5 times 3, 3 times. 1, 2, 3, 4, 5. >> 1, 2, 3, 4, 5, >> 1, 2, 3, 4, 5, pause. >> 1, 2, 3, 4, 5. 1, 2, 3, 4, 5, 1. did we end on your 1? >> whoa, you divided 16 into 3 equal parts. did you know you could do that? >> i'm dizzy. okay. well, we are going to end with a t high within a t high like a wheel that goes around and around and around. i want you to figure out there is a multiplecasion problem in here and i want you to see if you can tell us when we are done what it is. something will repeat 3 times. [applause] okay. which one of you figured it out? yes. >> 49, hum... >> i can see how you would say that, why do you say that? there is 49 of something. okay. did you notice the turns? the spins? h
